You are sitting on the floor like a good boy and step-mommy is standing above you showing you the contents of her wardrobe. What step-mommy doesn't realise however, is how ridiculously short her dress is, and that you can see step-mommy's thong on display. You watch as step-mommy absent mindedly scratches her ass cheeks and pulls her thong out from her ass crack. Go ahead and jerk off when step-mommy's head is turned, edge yourself for your unaware step-mommy.
